The Combined Joint Expeditionary Force (CJEF) is a Franco-British military force. It draws upon both the British Armed Forces and the French Armed Forces to field a deployable force with land, air and maritime components together with command and control and supporting logistics. It is distinct from the similarly named UK Joint Expeditionary Force.

The Combined Joint Expeditionary Force (or CJEF) is envisaged as a deployable, combined Franco-British military force for use in a wide range of crisis scenarios, up to and including high intensity combat operations. As a joint force it involves all three armed services: a land component composed of formations at national brigade level, maritime and air components with their associated headquarters, together with logistics and support functions.

The CJEF is not conceived as a standing force but rather as available at notice for UK-French bilateral, NATO, European Union, United Nations or other operations. Combined air and land exercises commenced during 2011 with a view towards developing a full capability. The CJEF is also seen as a potential stimulus towards greater interoperability and coherence in military doctrine, training and equipment requirements.

The UK and French defence ministries have jointly produced a User Guide (in English) to assist military staff operating at the operational and higher tactical levels of CJEF operations. This guide, jointly developed by the Development, Concepts and Doctrine Centre at Shrivenham, UK, and the Centre Interarmées de Concepts, de Doctrine et d'Expérimentations in Paris, has been published on the French Ministry of Defence website.

The CJEF is seen as being able to conduct offensive and defensive operations on land, in the air, and at sea. It is designed to be rapidly deployable and, once ready in theatre, to be sustainable for up to three months of operations as a stand-alone force; as well as having the ability to include other nations as coalition partners. The UK and France see the following as the most likely tasks for the CJEF:

The CJEF comprises strategic, operational and tactical level Command and Control elements, together with deployable sea, land, air and logistical components.

At the strategic level Command and Control (C2) is exercised via a CJEF Current Commitments Team (CCT) which takes its direction jointly from the UK’s Chief of the Defence Staff and France’s Chef d’État Major des Armées.
